[A non-secreting bladder paraganglioma. A case report].

The authors report the case of a 43 year old patient hospitalized for hematuria extending over eight years. Cystoscopy revealed an endovesical lesion which was resected and diagnosed as a non-secreting vesical paraganglioma. At operation, the cervical localization of the lesion was treated by total cystoprostatectomy. Starting out from this case report, the authors discuss the difficulties of diagnosing non-secreting vesical paragangliomas, the difficulties of assessing their malignancy and therefore the difficulties of treating them.
